This is a documentation subpage for Template:Doi. It may contain usage information, categories and other content that is not part of the original template page.

This template is used on approximately 28,000 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

This template produces a simple, standardized link to a digital object identifier (DOI).

((doi|10.1016/j.coi.2004.08.001))

which produces:

doi:10.1016/j.coi.2004.08.001

If the doi is freely-accessible, you can tag it as free with |doi-access=free

((doi|10.1038/495426a|doi-access=free))

which produces:

doi:10.1038/495426a

For instructions on how to use Wikipedia to automatically expand a DOI into a full reference complete with article title, author(s), date, journal name, volume, issue, page numbers, etc., please see User:Citation bot/use.

The parameter |nolink=, if set to any value (e.g. "true"), will suppress the "doi:" prefix in front of the identifier.

To mark a DOI accessible to the general public, use |doi-access=free.
